Apple light blessing, expansion and application of VCSEL vehicle market potential

If you want to talk about the most recent dynamic components, VCSEL (vertical cavity surface emitting laser) is among the best. With the iPhone X debut, 3D sensing module becomes a new generation of iPhone's most notable change, resulted in 3D sensing component of the core module of VCSEL has become the focus of. Apple and the degree of attention to the key components of VCSEL obviously, even for the laser chip manufacturer Finisar VCSEL to continue research and development work, and contribution of Finisar, Apple's move set off a market for discussion and for VCSEL.

In the light of Apple blessing VCSEL, seems to be the global technology star, however, VCSEL is not a new technology, it was put forward in 1980s, early in 1996 has been commercialized. This because Apple once again return to the spotlight, rejuvenation technology, is a kind of infrared laser technology.

Analysis of infrared laser and VCSEL Technology

First look at the development of infrared laser technology, compared with infrared LED, infrared laser cavity design has advantages of light, small divergence angle and high photoelectric conversion efficiency and data transmission speed. Because the infrared laser in the product design, the use of pulsed light, so it will not cause harm to human, with advanced technology and infrared laser products gradually into the sensing component, the application market from market to commercial and industrial consumer market.

In the infrared laser technology, and divided into VCSEL surface emitting laser, EEL edge emitting laser. Among them, VCSEL surface emitting laser with low threshold current potential, light beam with circular symmetry, high photoelectric conversion and high directivity source advantage.

Application of VCSEL to consumer electronics, the future car market potential

In recent years, VCSEL has been gradually applied to the consumer market, the current VCSEL surface emitting laser market application already contains a distance sensor, automatic focusing, 3D sensing (structured light and fly iris identification and ranging), air and water quality detection. Among them, the application field of 3D sensor and including home automation, robotics, wearable devices, computer games, television, automobile, biometrics and portable electronic products.

In addition, VCSEL can eliminate the spot (Speckle), light beam with circular symmetry uniform, easy to control the light emitting angle lens collocation of features, can also provide high resolution image for automotive night vision lighting, light source products become the best application of this. In addition to the potential applications in the consumer market, the future potential of VCSEL in vehicle industry, is also the focus of attention.

3D in the long-term development of construction scheme of the integration of supply chain alliance and the ability of the algorithm to test market

Dramexchange consulting LED Research Center (LEDinside) to sort out the current VCSEL information industry chain, to a VCSEL supply situation. The infrared laser chip upstream manufacturers including IQE, II-VI, EPISTAR, Hua Lijie, Wenmao, Hongjie branch, Lumentum, Finisar, Princeton, Optronics, NeoPhotonics, Philips Photonics, OSRAM OS etc..

But because of the hot X equipped with iPhone VCSEL, a substantial increase in demand, however, from a technical perspective, the trust must have excellent performance of VCSEL, infrared laser products are quite sensitive to temperature, as long as the temperature rises, there will be a substantial decline, and the quality of life of trust products has become a key factor, the maximum yield of products therefore, carrying on the mobile phone VCSEL products currently faced by product yield problems caused by lack of capacity.

The development prospect of VCSEL in 2018, but iPhone is expected to adopt VCSEL, the mobile phone brand camp has launched a supply chain alliance and cooperation, but how to break the patent barrier algorithm, and the third party application development, and even the whole 3D sensing module can effectively increase the price, it will affect the layout of VCSEL manufacturers next year with the development of.
